Evader® Gyro-While-Drilling Service

Sperry Drilling services' Evader® MWD gyro service was developed to fill a critical industry need: to provide faster, safer, more accurate drilling from offshore multi-well platforms. In the past, a wireline gyro was used to take a gyro shot to orient the pipe and survey the well. This activity can be time-consuming, as well as pose a health, safety and environments (HSE) risk. In between shots, the tool was steered without real-time orientation, increasing the possibility that the motor toolface could change direction and drill into a nearby well.

Benefits

Eliminates the need to use wireline gyros to orient or steer the drilling assemblies, which saves considerable rig time and provides for safer operations
